Application filed Hay l5, 1888. Serial No. 273,956. (No model.)

To @ZZ whom, t may concern: the lubricating cup or reservoir C, which is 5o Beit known that I, JOHN COMER, a citizen preferably formed of glass, in order that its of the United States, residing at Anderson, in contents will be exposed to View. l/Vithln the county of Shasta and State of California, this reservoir C one extremity of a tube D is have invented cert-ain new and useful Implaced, which: tube is bent to form a siphonproveniente in Lubricators for Shaft-Beartube and has its opposite extremity situated ings; and I do declare the following to be a within a-recess formed in the journal-box B. full, clear, and exact description of the inven- This Siphon-tube D is adapted to receive the tion, such as will enable others skilled in the wick E, which will obviously be of sufficient ro art to which it appertains to make and use length to extend from the oil in the reservoir the same, reference being had to the accomto the bearing to be lubricated.

To one side of the shaft A is placed cause the amount of flow of the oil to be regulated by the speed at which the shaft was running. Thus if the shaft was ata certain time running at a high velocity it would receive the same amount of oil as it would at another time when running at a low rate of speed, and, furthermore, it required considerable experience and calculation to place the reservoir at the proper height to feed the oil in proper quantities to the bearing to be lubricated. These disadvantages were owing to the fact that the reservoir was heretofore immovably located upon some portion of the machinery.

It will be quite obvious that with a device constructed after the plan` herein set forth the above disadvantages will not be experienced, owing to the fact that both siphonic action and capillary attractionare obtained, and that the reservoir is distinct from the journal-box, or any portion of the machine, and is placed movably in connection therewith. It will thus be quite obvious that the i amount of flow of the oil can be so regulated (by raising or lowering the reservoir) as to meet the various requirements occasioned by the running of the shaft at different rates of speedthat is to say, if it is desired to lubricate a shaft running anumber of revolutions per minute, the reservoir is raised to aheight suiicient to give siphonic action governed by full atmospheric pressure, and the capillary attraction ceasing the Wick becomes an absorbent plug, and in order to lubricate shaft-s running at a low rate of speed the said reservoir is lowered to a corresponding degree, and the action of the siphon lessening capillary attraction takes it place. ln regulating the flow of the oil care must be taken that vthe reservoir be not placed so high as to make the device a perfect siphon, in which event it would feed too fast, nor so low as to be compelled to contend against full atmospheric pressure, in which event it would feed too slow and would become unreliable.

Having now described my invention, what I believe to be new, and desire to secure by Letters Patent, and what I therefore claim,

isf A lubricator having both siphonic action and capillary attraction, for the purpose set forth, and comprising a reservoir adjustably mounted in juxtaposition to the bearing to be lubricated, a Siphon-tube extending from the reservoir to a point near said bearing, and a wick Within said siphon-tube and extending from the oil in the reservoir to said bearing. In testimony whereof l affix my signature in presence of two witnesses.
